METHOD AND TOOLS FOR PRODUCING RING FRAMES FROM A COMPOSITE MATERIAL |
摘要 |
<p>The present invention relates to a process for manufacturing composite ring frames for aeronautical fuselages by means of the application of the RTM technology to two preforms with C- and L-shaped sections manufactured using two tools (21, 55) in the following steps: providing the material; hot-forming planar rectangular laminates (41); hot-forming laminates of right angle section (51) on one part of right angle section of the first tool (21), placing an elastic membrane (55) and applying a temperature and vacuum cycle; hot-forming the preforms into a C shape (11) and L shape (13) on a second curved tool (55) by deforming said laminates of right angle section (51) thereon, and applying a temperature and vacuum cycle. The invention also relates to said tools (21, 55)</p> |
